SCREENSHOTS

Installation

Cocoapods:

pod 'SDWebImage-CircularProgressView'

Code examples

There are two parameters and unique prefix to easier finding.

• progressViewType - LinearPV or CircularPV. Choose the type of Progress View.
• progressView - If you init your own UIProgressView than put it there. It should be a class or subclass of UIProgressView.

- (void)nkv_setImageWithURL:(NSURL *)url usingProgressViewType:(ProgressViewType)progressViewType orCustomProgressView:(UIProgressView *)progressView;
- (void)nkv_setImageWithURL:(NSURL *)url placeholderImage:(UIImage *)placeholder usingProgressViewType:(ProgressViewType)progressViewType orCustomProgressView:(UIProgressView *)progressView;
- (void)nkv_setImageWithURL:(NSURL *)url placeholderImage:(UIImage *)placeholder options:(SDWebImageOptions)options usingProgressViewType:(ProgressViewType)progressViewType orCustomProgressView:(UIProgressView *)progressView;
- (void)nkv_setImageWithURL:(NSURL *)url completed:(SDWebImageCompletionBlock)completedBlock usingProgressViewType:(ProgressViewType)progressViewType orCustomProgressView:(UIProgressView *)progressView;
- (void)nkv_setImageWithURL:(NSURL *)url placeholderImage:(UIImage *)placeholder completed:(SDWebImageCompletionBlock)completedBlock usingProgressViewType:(ProgressViewType)progressViewType orCustomProgressView:(UIProgressView *)progressView;
- (void)nkv_setImageWithURL:(NSURL *)url placeholderImage:(UIImage *)placeholder options:(SDWebImageOptions)options completed:(SDWebImageCompletionBlock)completedBlock usingProgressViewType:(ProgressViewType)progressViewType orCustomProgressView:(UIProgressView *)progressView;
- (void)nkv_setImageWithURL:(NSURL *)url placeholderImage:(UIImage *)placeholder options:(SDWebImageOptions)options progress:(SDWebImageDownloaderProgressBlock)progressBlock completed:(SDWebImageCompletionBlock)completedBlock usingProgressViewType:(ProgressViewType)progressViewType orCustomProgressView:(UIProgressView *)progressView;

cancelCurrentImageLoad

If you're using the sd_cancelCurrentImageLoad method, you'll also have to call removeProgressView.

- (void)prepareForReuse {
    [super prepareForReuse];
    [self.imageView sd_cancelCurrentImageLoad];
    [self.imageView removeProgressView];
}

Customize UIProgressView by DataSource methods

1. #import "UIImageView+CircularProgressView.h"
2. @interface NKVTableCell () <ProgressViewDataSource>
3. [self.bodyImageV nkvSetProgressViewDataSource:self];
4. [self.bodyImageV nkv_setImageWithURL:url usingProgressViewType:CircularPV orCustomProgressView:nil];
5. In self (DataSource's class) implement method:

- (CircularProgressViewSettings *)setupCircularProgressViewSettings
{
    CircularProgressViewSettings *circularSettings = [CircularProgressViewSettings new];
    circularSettings.progressTintColor = [UIColor redColor];
    circularSettings.thicknessRatio = 0.2;
    return circularSettings;
}

Customize all UIProgressViews in app

[DACircularProgressView appearance].trackTintColor = [UIColor lightGrayColor];
[DACircularProgressView appearance].progressTintColor = [UIColor blackColor];
[UIProgressView appearance].trackTintColor = [UIColor lightGrayColor];
[UIProgressView appearance].progressTintColor = [UIColor blackColor];

You should know

• It uses SDWebImage and DACircularProgress.
• CirclePV type implements transparent view by default. Use appearance in AppDelegate or somewhere else to customize it.
• Custom progress bar is a priority for other types. Otherwords if you choose LinearPV and then add orCustomProgressView:(UIProgressView*)yourCustomProgressView than it would be your custom ProgressView.
